- Be it known that I, {Dz-un ons HENRY, a citizen of the French llopuhlio, and resident of Paris, France, have invented. cormin now and useful Improvements in the Pr cess of Making a Cold Varnish Dye, of which dis fol-- lowing is aspecilinstion.

The invonti on relates to an improved pr css of making a. cold dye; and it 0011. the trsatlnont oi dyes of j 4 or Combined colors to render them tIlgGitidl, so that asingle dye will when applied give oil or produce a great vz'iricty of colors other than and including such primary color or colc' The process is carried out in {timnec With any or the various kinds ol' organic. dyes before the smno has been uppiii'd to the fabric 01 the material to be colore To this 011d tho invention consi i n mi):- ing it cold dye and sizing agent or varnish and exposing the resultant solution to tho action I of a reagent.
